Consumers are purchasing less physical items from their mobile devices and opting for desktop computers instead, says Forrester Research.

The percentage of online sales made via mobile phones declined from 43 percent in 2016 to 36 percent in 2017, according to a report called “Mobile Shopping Is Stalling, But Don’t Panic” made available to AListDaily.

Forrester Research found that US adults are increasingly turning to home computers to do their shopping instead of mobile phones, despite considerable investment by retailers in the platform.

In 2016, 21 percent of US online adults with a mobile phone said they purchased physical goods on mobile phones at least weekly, but in 2017, that figure fell to 16 percent. In fact, the percentage of US online adults who said they don’t even own a mobile phone more than doubled from five percent to 11 percent between 2016 and 2017.

When asked why US adults steered clear of mobile shopping, the most popular answer at 51 percent was that using a computer is “easier.” Respondents are also creatures of habit, with 46 percent saying that they are used to making purchases on a computer and therefore do not engage in mobile commerce.

“Digital business executives should carefully analyze the objectives that they have for their mobile investments and recognize the limitations of the mobile channel,” wrote Sucharita Kodali, Forrester Research vice president and principal analyst for ecommerce and channel strategy.

Kodali attributes slow mobile commerce adoption to cumbersome mobile sites, requiring too many keystrokes to complete a purchase. The report also warns retailers not to assume that these trends will change as younger users become consumers.

“There are few ‘no PC’ households in the US,” Kodali said, “and we don’t anticipate that changing as young children are becoming accustomed to larger—not smaller!—screens.”

As for other countries, however, mobile commerce is anticipated to thrive. Less access to computers will most likely translate to mobile commerce, Forrester noted, especially in countries like India and China.
